What race organizers bill as the largest college campus in the world — 28,000 acres — is the setting for the running of the Berry Half Marathon & 5K, which takes runners on a tour of this college’s green, hilly, wooded campus set in the foothills of north Georgia’s Appalachian mountains. Relatively fast and flat — with the exception, of course, of the big uphill and downhill stretch from the main campus to the mountain campus in the middle of the race — the out-and-back course also includes several rolling hills throughout the route, which starts and finishes at the Ford Buildings on Berry’s campus.
